Graded paint finish: Occasionally we receive frames with a paint finish that doesn't pass our stringent visual inspection. The frames have been moulded and manufactured perfectly and have passed our structural integrity tests, they just have marks in the paint finish. In the case of these Maratona frames, that means they have cloudy paint imperfections beneath the gloss coat. They're a bit milky! You'll have to look at them in the right light to find the marks, and it has absolutely no effect on the performance or durability of the bike, but it does mean we've cut the price. So grab a bargain, full-fat or semi-skimmed get ready for the Milk Race.

Frameset: Any bike is only as good as the roads you ride on and that's why we've designed the Maratona to help smooth out the worst road surfaces. By precisely engineering frame tube shapes and carbon layup, we've created a frameset with subtle vertical compliance in the rear triangle for day-long riding comfort. Blending superior grades of carbon fibre in specific frame locations helped us to trim excess weight from the frame and create a comfortable bike with neutral handling that corners like it's on rails and climbs like a true mountain goat. Inspired by Jamie Burrow's victory in the Maratona dles Dolomites it's a truly versatile performer.

Longer chainstays and a taller front end contribute to the Maratona's relaxed riding position while an oversized tapered headtube and monocoque fork ensure sure-footed handling and braking confidence. Comfort is only half the story behind the Maratona, it's also incredibly efficient. The Maratona dances up climbs and can be relied on to help you get to the cafe before the last seat is taken. With Di2 compatible cable routing there's plenty of scope for a future groupset upgrade if you were ever that way inclined.

Groupset: Shimano's 105 5800 groupset introduces 11-speed gearing at a new, even lower price point. 105 features all of Shimano's top-level technology and performance, trimmed and trickled down to a seriously competitive price point. Shifting finesse, ergonomics, drivetrain efficiency, and durability is second to none with 105. It provides some serious competition to other brands 11-speed groupsets.

The Maratona's Shimano 105 pick comes with a wide ratio 11-32 cassette so you'll have plenty in reserve for the steepest climbs. Shimano's smooth acting 5800 brakeset takes charge of pulling you up to a halt and provides huge amounts of brake modulation for effortless stopping power. Featuring a Hollowtech 2 chainset with compact 50/34 chainrings that are light on weight and high on stiffness the Shimano 105 groupset offers faultless performance and durability that you trust mile after mile, season after season.

Wheelset: Shimano RS Asymmetric Shimano sweat the details so you don't have to. Lightweight rims are laced to freespinning hubs with high quality spokes to ensure that your wheels accelerate quickly to the slightest pedal input. An asymmetric rear rim profile helps to centre the load from the spokes and allows for a stronger ligther wheel that will stay truer for longer. The RS wheelset offer a real taste of the high end.

Finishing Kit: Selcof and San Marco A lightweight bike like the Maratona deserves a high spec finishing and we've built it up with a selection of the very best parts in the Selcof finishing kit bag and topped it off with one of San Marco's best selling saddles. Everything is colour cop-ordinated from the rims to the cables to the saddle and bar tape, there's no smarter 105 bike on the road.

Big miles, long rides, and rough roads the Maratona will tame them all with its magic carpet ride. Designed to tackle the challenges of Gran Fondo riding and epic days out in the Alps, Dolomites and Pyrenees, if you're on the hunt for a new sportive bike put the Maratona on your wish list.
